Is there any public or private sources of LIDAR data for the city of Chicago? Searching online has not lead me to any sources, and I am unsure how the commercial world of LIDAR works.
The LIDAR point spacing would need to be at an interval that I can use to estimate the building height from the footprints.

Does Chicago belong to a council of governments? Often a COG facilitates LiDAR contracts by pooling together funds from participating municipalities. Otherwise you might try the City of Chicago's GIS department: GISTeam@cityofchicago.org
